Hi. I am working with a Mac Pro 4.1 late 2009 , 8 core 2,26 , 32 gb ram , hd3 pcie on pro tools 10 hd. When I start my computer and running pro tools the software freezes while initializing dsi hardware. Sometimes i need to shutdown my computer 10 times. Every time I shutdown the computer I remove the cards and place them again sometimes i have to remove them even 10 times before it works. The digitest shows no errors. Any ideas why is this happening? anything would be helpful thanks

Whenever I see someone post with the specs of a 2009 a MacPro, I always want to jump in and try and help them out! Just want to make sure you realize that you can upgrade that 8 core to a 12 core, then upgrade the firmware to make it a 5.1 Mac Pro. After you do that the geekbench scores will be over 30,000. And turn that computer into a monster of a machine all for less than, about $400!

I am more than happy to help you out with the process, just send me a private message, and we can get the ball rolling.

Try holding down the "N" key on your keyboard just after you click to launch PT and keep it held until the audio interface selection page pops up and then make sure the correct audio interface is selected, (if it is already choose a different one to get into PT then close relaunch and go back in and select the one you want again.
If this still doesnt help, trash your preferences and repair the disk perimissions and try again.
